The angle that the effect length light of optical element main body is propagated.The long main body accurately adjusted can obtain optical element
Acute angle.Vice versa, and short main body makes optical element obtain obtuse angle.The size of the main body must be by optical element incidence surface and going out
The geometry of reflective surface is supported.
As shown in Figures 2 and 3, reflector 12 is added to optical element OP, so as to which sunshine light beam 11 is reflexed into suction
Receive device 10.The light beam of optical element side surface 7 is reflexed to by reflector 12 towards can (part from optical element exit surface 6
Ground) around the absorber reflection of optical element.As shown in Fig. 2 being incident on optical element outgoing with the angle [alpha] relative to optical axis OA
The sunshine light beam on surface 6 is directed into side surface 7 due to the refractive index of optical element, and by due to refringence
Caused total reflection, is reflected by reflector 12 towards the absorber 10 around optical element.In order to more effectively utilize optics member
Part surface, it is possible to reduce the quantity of reflector.
As shown in Figure 3, it may be considered that the incidence angle of the refractive index and sunshine light beam of optical element and air, to design
Reflector, and sunshine light beam allows for being totally reflected from surface.
As shown in figure 4, the single reflector of the incidence surface 5 close to optical element can be designed.By also due to
It is attached to total reflection caused by the refringence at the single reflector 13 of optical element incidence surface 5, it is all to be imported into
Sunshine light beam is reflected through side surface 7.
As shown in Figure 5, it may be considered that the incidence angle of the refractive index and sunshine of optical element and air, to design reflection
Device 13, and sunshine allows for being totally reflected from the surface.By with close to the single of optical element incidence surface 5
Reflector 13 (referring to Fig. 4), it is not necessary to form reflector along whole optical element side surface 7.Can be optical element OP's
Single reflector is formed at bottom.Reflector 13 can be configured to the sun with an angle of the optical axis OA relative to optical element
Light reflexes to absorber 10, and the angular range is in 20 to 70 degree, preferably in 30 to 60 degree, most preferably in 40 to 55 degree.
Reflection can be caused by the internal reflection in optical element.Reflector 13 can have reflecting surface, and sunshine is reflexed into suction
Device is received, the reflecting surface has an angle relative to the optical axis OA of optical element, and the angular range preferably exists in 20 to 70 degree
In 30 to 60 degree, most preferably in 40 to 55 degree.
In addition to the sunshine reflected from reflector, the absorber thin slice around optical element can also be absorbed from light
Learn the sunshine on the other surfaces of element.By this way, reduce and bright circuit board or light source is incident on lesser degree
On sunshine back-reflection rate.Absorber thin slice around optical element can have different geometric profiles.Absorber
Surface can be by being made with dark different materials, and assimilation effect can also be by providing with different surfaces feature
Absorber surface improves (Fig. 5).
Absorber can be fixed on the optically inactive surface of optical element with adhesive 16.Absorber and reflector 12,
The distance between 13 can be more than 0,0.1 between 50mm, preferably 0.2 between 10mm, and most preferably in 0.5 He
2.5mm between.
Adhesive 16 may be used to optical element and fix on the front surface, and adhesive may insure the watertight of information system
Property.
In this way it is possible in an efficient way using all guiding surfaces of optical element.Be incident on arc surface and
Light beam on smooth surface is more strongly reflected with its incidence angle, rather than from surface homogenous diffusion.It is several due to arc surface
What structure, the different angles that the reflection is also observed with observer are formed.
In Fig. 6 a, Fig. 6 b and Fig. 6 c, it is illustrated that with the incident sunshine 11 (ginseng of angle of 10 degree relative to optical axis OA
See Fig. 6 a) by from the mode of arc surface back-reflection (referring to Fig. 6 b).When right-angle view arc surface, sunshine reflection performance
For along the straight line dazzle on surface, and it increases the amount of back-reflection.As shown in fig. 7, in order to prevent sunshine from reflecting, being formed
Geometry 14.Geometry 14 is reducing the back of the body of sunshine 11 in the desired angular ranges 15 of optical axis OA (referring to Fig. 6 c)
To reflection.By the shape, the back-reflection direction of the sunshine light beam reflected from exit surface 6 is changed, so as to expect
Angular range 15 in reduce back-reflection amount.Geometry can be formed as not reflecting relative to optical axis OA preferably -10
Any sunshine injected into the desired angular range 15 of+20 degree.
The angle of declination of geometry 14 can make the accumulation rate of snow and dust on exit surface bottom minimum.Therefore, protect
Holding optical efficiency becomes possibility.
Needed according to system, it is necessary to which the optical element being fixed on the preceding surface of flexible message system and light source is accurately right
Standard is simultaneously correspondingly attached.Otherwise, the light source shifted due to misalignment or in good time, it may not be possible to obtain desired optical value.
As shown in figure 8, light source is attached to electronic circuit board 1 thereon by means of screw and by from flexible message system
The metal bush 17 that inwardly promotes of preceding surface 3 be fixed on preceding surface.By this way, light source can be by accurately solid
It is fixed, and in three dimensions with optic alignment.Due to the metal structure of bearing shell, the knot with longer life can be formed
Structure.In addition, with by be tightened to optical element surface formation structure on the contrary, can use with reduced size optics member
Part.The present invention will be produced as being suitable for the size of variable information system, and for increasing contrast, without damaging optics effect
Rate.
Although the specific embodiment of the present invention is described above, it should be appreciated that the present invention can be with addition to description
Mode implement.The pigment with low reflectance factor can be used to cover for example, the preceding surface of light source and lens can be placed.It can subtract
Few volume reflection produced in lens surface.Lampshade can be formed on optical surface and by adding the prolongation on lens
Increase contrast, however, this prolongation produces irregular surface on the front surface, thus cause the accumulation of snow and dust,
This can reduce optical efficiency.
Another method for increasing contrast can include the use of colored lens.Lens are produced as having and radiation
Color identical color so that lens absorb solar spectrum in other colors.However, for polychromatic source, it may not be possible to
Using this method.Furthermore, it is possible to by means of nanometer (and micron) rank formed using fine surface treatment in material
Structure, to reduce the amount of the back-reflection produced on the surface of the lens.On the other hand, this method is because its requirement is very accurate
Processing and it is fairly expensive.
ARC can be set on the surface of the lens.Although the wave-length coverage that can be obtained according to this method in calculating
It is interior to obtain sufficient result, but for the sunshine light beam with wide wave-length coverage, it may not be possible to obtain effective result.It is right
In wider wave-length coverage, laminated coating can be applied, but therefore this method becomes fairly expensive.Moreover, coating can be by day
The influence of gas bar part, and with the passage of time, coating starts the surface peeling from optical element.In order to be produced with low cost,
Changed by the way that lens are made with geometry, effective contrast can be provided, without disturbing desired angle, radiation and color.
